Definition
Facial paralysis is the total loss of voluntary muscle movement of one side of the face.
Considerations
Facial paralysis in adults is often due to Bell's palsy. This disorder (probably derived from a virus) usually affects one side of the face causing a drooping mouth, drooling, and excessive tearing from one eye. While the facial distortion usually improves over time, there may be some permanent deformity. Sometimes there is loss of taste on the affected side of the face. Sound may also be louder on the affected side.
In facial paralysis due to stroke, the eye on the affected side can be closed and the forehead can be wrinkled. This is not possible with Bell's palsy. Other muscles on one side of the body may also be involved with a stroke.
Facial paralysis due to a brain tumor generally develops gradually with accompanying headaches, seizures, or hearing loss.
In newborns, facial paralysis may result from birth trauma.
Common Causes
- Bell's palsy
- Stroke
- Brain tumor
- Sarcoidosis
- Lyme disease

Home Care
Treatment depends on the cause. Follow your health care provider's treatment recommendations. Sometimes steroids and acyclovir may be given depending on the cause.
If the eye cannot be fully closed, the cornea must be protected from drying out with prescription eye drops or gel.
